I totally agree, but I have a ~111,000 line application that's built on
widgets that I want to get ready for a post-widget GWT. :)

Elemento's the route I'm already hoping to go. I've thrown together a quick
minimal test to see whether Widgets and Elemental2 stuff can live side by
side, and everything renders, but events don't seem like they get plumbed
through to GWT widgets if I don't attach to the RootPanel:
public class ElementoWidgetTest implements EntryPoint
{
@Override
public void onModuleLoad()
{
// This is Allen Sauer's GWT logging thing
Log.info("Hello world.");
Document.get().getBody().removeAllChildren();
// Quick and dirty bootstrap navbar
HTMLElement navbar = nav().css("navbar navbar-inverse navbar-fixed-top").add(
div().css("container-fluid")).asElement();
navbar.addEventListener("click", (evt) -> {
Log.info("Clicked on the navbar!");
});
// Trying to attach GWT widgets to the dom without RootPanel/RootLayoutPanel
FlowPanel panel = new FlowPanel();
panel.getElement().getStyle().setPaddingTop(70, Style.Unit.PX);
Button button = new Button();
button.setText("Hi, I'm a button.");
// I've attached a click handler here, but I never see the log statements.
Seems
// like events don't get plumbed through to widgets if I'm not using RootPanel
button.addClickHandler(event -> Log.info("Button clicked"));
panel.add(button);
Elements.body().add(navbar);
Elements.body().add(Elements.asElement(panel));
}
}
I see logging entries from clicking on the <nav> element I added, but the
GWT Button doesn't respond.
